BOILER SEDIMENT-SEPARATOR.

incassa.

To all whom t may concern.'

Be it known that I, ALFRED A. OLSON, citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boiler SedimentSeparators, of which the following is a specifica tion.

rThis invention relates to improvements in means for separating scale and other solids from the water in a steam boiler, said means being adapted to facilitate the cleaning out of the separated solids.

The especial object of the improvements embodied herein is to provide baffle plates adapted to be placed in the water drum of an ordinary boiler' and so constructed and arranged as to facilitate the removal or blowing out of the sediment collected in the bottom of the drum below said plates.

A further object is to provide means whereby the baffle plates may be held against accidental displacement in the drum of the boiler without requiring any holes to be made in the walls of the drum for bolts or rivets.

A further object of my invention is to provide means for holding the baffle plates in operative position which holding means may be readily detached from both drum and bailie plates to facilitate the removal of the plates for the purpose of repair or substitution.

A further object of my invention is to provide baille plate holding means adapted to be adjusted to boiler drums of diierent diameters and which cooperate with the rivets used in securing the ends of the drum to the side walls thereof.

A still further object of my invention is to provide baille plates for the purpose mentioned which are readily accessible through the manhole of the drum and which can be so manipulated as to permit a stream of water under pressure being thrown upon all parts of the surface of the drum below said plates.

Having the foregoing and other objects of general utility in view, I have designed the appliance shown in a preferred form in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view in a horizontal plane of a boiler drum of simple form; Fig. 2 is an enlarged crosssect'ional view on line 2 2 of Fig. 1; Fig. 3 is an enlarged sectional view on line 3 3 of Fig. 1; Fig. t is a view partly in section Specification of Letters Patent.

and partly in end elevation of a boiler equipped with my appliance showing one form of holding device for the baffle plates; Fig. 5 is an end elevation partly in section taken at the manhole end of the boiler drum; Fig. 6 is an enlarged cross sectional view on the line 6G of Fig. 1, and Fig. 7 is a view of a boiler of well known type, indicating the general arrangement of my improved sediment collector for boilers.

Referring to the details of the various views above mentioned, the reference numeral 8 represents the side walls, 9 one end wall, and 10 the opposite end wall in which is the manhole 10a, of a boiler drum of ordinary construction. The ends 9 and 10 are secured in place by the usual rivets 11.

The sediment separator and collector is made up chiefly of a series of plates 12, 13, 14, 15, 16, 17, and 18, respectively, which are connected together in the manner hereinafter described in detail. The plate 12, which is adjacent the inner end 9 of the drum, is bent at right angles along its inner longitudinal margin to form a downwardly extending flange 121L (see Fig. 2), and the opposite edge of said plate rests against. the inner walls of the drum S.

Secured to the fia-nge 12d by bolts 24, is an angle-bar 28, the horizontal ange of which extends outwardly from the plate 12 and partially bridges the opening between said plate and the opposite plate 15. The plate 15 is bent upon itself to form a parallel flange 15a. The plates 12 and 15 are connected near one end by a hinge made up of straps 19 and 20 and a bolt 22 which engages eyes formcd on the free ends of said straps. The straps are bolted to the respective members by bolts 21, 21h, and nuts 21, the said nuts being on the under side of the plates. The plate 12 is further supported near the end opposite the hinge connection with the plate 15, by a leg lf3 which is connected with the plate 12 by the bolts 211.

The plate 13 is of the same general form and size as the plate 12, and is provided with a corresponding flange 18C, and also with a, series of holes 13, and has a cutaway portion 13b, said holes and cutaway portion being located near and along the outer edge of the plate. The plate 1G which is opposite the plate 13, has the apertures 16a, 1Gb, corresponding to 13, 13b, and is connected with the plate 13 by the strap hinges 19, 20, which correspond to those connecting the The plate 13 has bolted thereto an angle 23, and extending for a portion of the length of this angle bar, is an angle plate 26 which is bolted to the horizontal portion of the angle 23 by bolts 25 and the other angle of the plate 26 extends upwardly and serves asa rest and support for the plate 16, as clearly shown in Fig. 3. rI'he plate 13 is also equipped with a leg 43, and it will be noted that the ends of the plates 13 and 16 overlie the adjacent ends of the plates 12, 14, 15, and 17, respectively. The plate 14, which is arranged between the plate 13 and the manhole end of Vthe drum, corresponds with the construction of the plate 12 above described, and is hinged to the plate 17 by the hinges 19, 20, and is also equipped with an angle plate 23 and a leg 43. It will be noted, however, that one of the hinges 19, 20, is not at the end of the plate 14, but is nearer the middle thereof, and it will be noted that the plate 17 is approximately one-halt' the length of the plate 15 with which it otherwise corresponds. The plate 18 which completes the baille element opposite the plate 14 is formed with a downwardly extending flange 18a along its inner edge in which holes are provided to receive rods 27, which at one end, are connected with the plate 14 nuts 28 von the under side of said plate and at their opposite ends are connected with the plate 18 by eye-bol`ts18b. The rods 27are bent upwardly as at 27a so as to support the plates 18 at the same angle as the plates 15 and 16.

At the end of the plate 12 adjacent the end wall 9 of the drum 8, is bolted or riveted a bracket composed of a plate 29 and a yoke 30 bolted to said bracket by bolts 31. This yoke, as shown in Fig. 4, receives a pipe 32, the upper end of which is threaded as at 32, and the lower end of which is adapted to receive the projecting head 32b of one of the rivets which secures the end 9 to the sidesof the drum 8. Connected with the upper end of the pipe 32 bya coupling 34 lis a short pipe section 33 the inner end of which is threaded as at 33a to engage the threaded coupling 34 and to receive a lock nut 35. The upper end ofthe pipe section 33 is adapted to engage a projecting rivet 33h.

As shown in Fig. 5, the end of the plate 14 adjacent the manhole 10a, is equipped with a bracket 36 and a yoke 37 'corresponding to the bracket and yoke above described, and the yoke 37 embraces a pipe section 39 which is bent as at 39a to conform to the adjacent edge of the manhole opening 10a, and the upper end of the pipe 39 is threaded as at 39b and its lower end engages the proj ecting rivet'39C in the bottom wall of the drum 8. A short pipe section 40 having threads 40a on its lower portion, is connected with the pipe section 39, by a coupling 42, the threads Vand thus force the solids now/,eee

of which are right and left hand so as to engage the correspondingly threaded portions of the sections 39, 40, whereby the turning of the coupling 42 will tend to expand or contract the sections relatively to each other, depending upon the direction in which said coupling is turned. The lock nut 41 on the pipe section 40 serves to hold the parts against accidental disengagement. In the bottom of the boiler midway its length is the usual drainage or blowolil opening 45 from which leads exteriorly of the drum, a discharge pipe 45a,psee Fig. 7. In the type of boiler shown in Fig. 7, and in many forms of boilers having drums similar to those herein described, that is to say, having inlet pipes 46 and outlet pipes 47, the water is introduced into the drum under pressure from the usual pump or as a result of the city pressure, and falls downwardly against the baille plates 15, 16, 17, 18, from which it is deflected upwardly, and as it is converted into steam is carried oli' through the pipes 47, the water being given a circulatory motion.Y The scale or other solids or impurities in the water will pass through the opening 16a, 1Gb, and through the openings between the inner edges of the several baille plates, which openings extend longitudinally throughout the length of the plates except where the guard plate 26 is arranged, and will be caught or pocketed in the space below said plates and will be prevented from passing upwardly by the angle plates 23, the langes 12a, 13G, and will therefore accumulate on the bottom of the drum below said plates until flushed or blown out in any of the well kno-wn ways and carried out through the opening 45 and the pipe 45a. Y

Then it is desired to remove the sediment and impurities from the boiler, the manhole plate 10b will be removed by disconnecting the stirrups 10C in the usual manner and the operator will reach in through the manhole and slide the plate 18 upon the guide rods 27 so that said plate will pass above the adjacent portion of the plate 14. The operator will then enter the drum and turn the plate 16 on its hinges over the plate 13. He will then turn the plate 17 over the plate 14 and the plate 15 over the plate 12. Vhen in this position, a stream of water from the flushing nozzle can be directed against all4 portions of the bottom of the boiler Idrum downwardly through the opening 45 and out through the unnecessary the cutting or tapping of the walls of the drum at any point for the purpose of holding the plates in their operative position. It is also obvious that instead ofhaving the plates 15, 16, 17, hinged as shown, they may all be of the sliding character indicated by the plate 18, and accomplish the same results that the hinged connections accomplish. By using the form of strap hinges described and bending the edges of the plates as indicated in Figs. 2 and 3, I am enabled to use lighter weight material for said plates than would otherwise be practicable. By guarding the opening 4:5 with the plate 26 I prevent the blow out water from discharging directly into said opening, and thereby cause it to be distributed over the entire surface of the bottom of the boiler through the end and center openings, thus effectively carrying off the sediment and scale from the boiler surface below the plates.

Having thus described my invention what `I claim as new and desire to secure by Letters Patent, is
